Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	Grant to reporting person of non-qualified stock option pursuant to the Alkermes, Inc. 1999 Stock Option Plan.
(2)	The option becomes exercisable in equal annual installments over a four-year period, at the rate of 25% per year commencing one year after the date of grant.
(3)	On 12/12/2006, Mr. Ehrich was granted 2 stock options, an option grant of 20,000 shares (19,823 NQ and 177 ISO) and a 2nd option, pertaining to Mr. Ehrich as an Inventor, for 500 shares (NQ). The original Form 4, filed on 12/13/2006, omitted the grant of 500 shares. This amendment is intended to correct that oversight.
